Auralization
by convolution
•The basic method consists in convolution of a
dry signal with a set of impulse responses corresponding to the required
output format for surround (2 to 24 channels).
•The convolution operation can nowadays be
implemented very efficiently on a modern PC through an ancient algorithm
(equally-partitioned FFT processing, Stockam 1966).
